Sega Sports' World Series Baseball, or simply World Series Baseball, is a sports game developed by BlueSky Software and published by Sega for the Mega Drive/Genesis. It is the first game in the series and was originally released in 1994. A version for the Sega 32X, World Series Baseball starring Deion Sanders, would follow in 1995.
The first title in the World Series Baseball series, the game was a major advancement in Genesis baseball games in that not only did it include licensed players and teams, but also contained relatively accurate gameplay for the time.
Several more games were released in the series following the original, up to World Series Baseball 2K2 on the Xbox. After that, Sega contracted with 2K Games to take over their sports game contracts and the series has continued as the Major League Baseball 2K franchise, which thanks to 2K's contract with Major League Baseball is one of only two MLB video game series currently on the market (the other is Sony Computer Entertainment's MLB: The Show series that only appears on the PlayStation systems).
